摘　　要：随着武器威力的大幅度提高以及内弹道理论的进一步发展,在武器研制过程中对弹丸在膛内现象的测试提出了越来越高的要求。本文在介绍微波干涉测量技术的基础上,分析了微波干涉信号的基本特点,提出了利用小波变换等方法对干涉信号进行预处理,不仅可以有效地从原始信号中提取出由弹丸运动所产生的微波干涉信号,同时也提高了数据处理结果的精度。With great increase of the weapon power and further development of inner ballistic trajectory theory,test of pill phenomena inside the chamber is required of higher and higher demand in the process of weapon development.Based on the measuring principle of microwave interferometer,the elementary characteristics of microwave interference signals are analyzed and the methods based on wavelet trans- form are put forward to preprocess the signals,which can not only extract the microwave interference signals by the pill movement effectively from the initial signals,but also improve the accuracy of data processing result.
